".Oneobject of the invention `is to provide a track Vcarrying lever`adapted .for insert-ion under ,ther rail and movable transverselythei-eoffor shifting the tracklfor ,aligning purposes.

A further :object of the `invention is to effectythe movement ofsaidvlever throu h the medium'ot a rock arm so' as to `limit t e raisingofthe levcrfWhen` aligning the track to prevent undue lifting ofthe tiesfrom the roadbed tof prevent ballast entering beneath the ties fordisturbing the foundation therefor.

\ A furtherobject ofthe invention is toprovidemeans having a ratchetaction'to allow for a step by step" application of power for shift-ingthe raiIsand ties and retaining the track in its shifted'positio'nsbetweeneach applicationof power. f

A further object of the invention is to obtain this ratchet action:`through Ithe 'medium of an inclined rack on which the levera e applyingbarhas a stepbyl step action in t e ehittingof the'track Af stillfurtherwobjectl of the'invention is to havethe' track carrying *leverconnected with the2 leverage-applying bar closely adjacent the fulcruniof the latterA1 so as vto increase the leverage applied by the'bar inaligning the track. i *The invention consists further in the`mattersihereinatter described and claimed.

As shown in the"drawings, thetrack yliner ot the invention has a`relativelyflat base plate 1 provided on its under side-with ribs COOK,RESIGNEIL LINER.

The ribs 2, 2extendialong thevsides of the platel and, as sho-Wn in Fig. 4,haveinclined inner sides tohoIdandJpaCk the roadbed between them andthusbuild up a foundation to resist the downward pressure onE theplate. Theribs 3. 3 extend pcrosswise of theplate 1 and serve to prevent endwiseshifting of the base plate in the `useot' thedevice." These ribs, asshown in Figs. 1 and `2,.' are substantially V-shaped y solas tofwedgeinto the roadbed.

The lowerend of theiarm 7-pivots or rocks on: an axis member9 extending between and supported by the webs 6, y6,-as Shown. Saidlever Lthas a cross-web 10 in itsichannel at i, its outer `end toprovide la continuous bearing tori the `roller 5 inl the endwisemovement otthelever4.` i

i Tov the rearof the arm 7 is an` actuating lever llpreferably made insocket form to receive an actuating bar12, such as a standa-rddtrackbar.yThe i lever 11 is connected with theffaxis member 8 by a pair of links13,\\13,` and the forward or fulcrum end of Asaid Vlever .11 actsuonanupwardly inclined rack' means 14' for imparting a step by u step*artionffork lifting andishiftlng a track lrail 1 The forward end of theactuating lever is bifurcated, as shown, so as to have a pair of endportions for engaging the pair of racks 16 and also to receive the pairof links 13, the latter having pivotal connection with the lever 11 by atransverse pin 18. Pawls 19, 19 are carried by the axis member 8 toco-operate with the steps 17 in the actuation of the device. These pawlsare connected together by a transverse web 20 so that they operate inunison.

In use, the device is inserted under the rail 15 until the lever4'contacts with the adjacent edge of the base flange of the rall, asshown in Fig. 1. If the space between the base flange of the rail andthe roadbed is at the minimum, say three inches, the lever 4 is in aposition substantially horizontal and with the pawls 19 free of thesteps 17 and resting against the vbase plate 1 at the lower ends of theracks 16, as shown in Fig. 1. This will enable the liner to be insertedunder the rail so as to bring the adjacent edge of the rail preferablymidway between the axis of the roller 5 and the axis member 8. At thistime the forward or fulcrum end of the actuating lever 11 is in positionto engage the lowermost of the steps 17.

On raising of the bar 12, the lever 11 fulcrums on the lowermost steps17 and rocks the arm 7 forward to raise the rear of the lever 4 andthereby lift the rail 15 and its attached ties to break contact of thelatter with the roadbed to lessen the resistance to the shiftingl of therail and its ties in the aligning of the track. The pawls 19 ratchet upthe first.l steps 17 and hold the lever 4 in yits raised position toretain the rail 15 and itsties'raised. With the pawls 19 retaining theload, the lever 11 is free so that its outer end may be lowered to raiseits fulcrum end to engage the next set of steps 17,

Athe links 13 gravitating inward to automatically swing the fulcrum endof said lever into said steps. This allows for another application ofpower or leverage to the lever 4 to advance it farther forward and carrythe rail 15 and its attached ties therewith.

each successive power operation of said lev-y er 11, thereby allowing asingle workman to exertconsiderably more leverage or power on the trackto shift the same than with track lining devices as^ heretofore made. Byholding the track from receding between each power operation of thelever 11, the track is Vretained in its various intermediate shiftedpositions, thus making the device more effective. Moreover, the trackdoes not spring back to jar and loosen the dirt or ballast of theroadbed to enter beneath the slightly raised ties todisturb thefoundation therefor.

As the advance of the lever 4 increases, the lifting of the leverdecreases as the arm 7 approaches a vertical position. This is anotherimportant feature of the invention because the ties are not lifted highenough to permit ballast to enter between them and the roadbed todisturb the foundation for the track. In the initial application ofpower to the device when the lever 11 engages the lowermost steps 17.the base plate 1 is forced into the ground so as to obtain a proper seatuntil sufficient resist-ance vis obtained to lift or support the railand attached ties in the advanceof the lever 4. Consequently.` by havingthe track engage the lever 4 in the midway position heretoforementioned, the amount of lifting given the track is necessarily limited,due to the loss caused by base plate 1 being pressed into the ground.and therefore undue lifting of the track to build up ballast beneath theties is avoided. The trackis therefore shifted substantiallyhorizontally in the advance of the lever 4 so that no op ortunity isoffered for building up of bal ast beneath the ties. i

It will be noted that the forward or fulcrmn end of the lever 11 onengaging the steps 17 exerts a downward pressure on the base plate 1 .onone side of the rail in the upward movement of` the lever, while theweight. of the rail on the lever 4 is exerted downward on the plate 1 onthe opposite side of the rail through the roller 5, thereby practicallyequally distributing the load on the base plate. The pawls 19 engagingthe racks 16 adjacent the fulcrumend of the lever 11, also effect anequal distribution of load whensaid lever is free.

The axis member 9 has a fixed position on the base plate 1 and does notchange inthe actuation of the device.4 The roller or bearing 5 is alsoin a fixed position on the base plate and vdoes not change`l as thelever 4 advances or recedes over the same. This pro# vides a fixeddistance between the bearing 5 and axis member 9 so that the distancebetween tlie outer end of the lever 4 and the axis member 9varies in therocking of the arm 7. As the arm 7 rocks or swings forward, that is,toward the" rail 15, the latter carried by the lever 4, and as the railapproaches closer to the fulcrum 5 of said lever the axis member 9 sothat thelever 11 cannot move the arm 7 beyond asubstantiall up-Y ri htor vertical position, as shown in `ig. 2 T is prevents the lever 4fromcarrying the rail beyondthe bearing 5 to overbalancev the device andcanse the leverageA exerted through the same to beeorneinefl'ective.

With a device of the general size. show-n in the drawings, a singleworkman `inayexert a leverage as follows. The distance between` lyopposite so as to effect [proper shifting `to place.

theraxismember 18 and the fulcru'm endLof the lever 1'1 is approximately1% inches'. A standard .trackY bar, such as 12, is about 66 inches long,and with three inches'between the pointed end of this bar and thefulcrum end `of the lever makes an overall length y.of 69`inehes. Thisprovidesa leverage exerted through the lever 11 and bar"12 (the latterbeing an extension of the former) of 46 to 1. When the lever 4"engagesthe rail 15midway between the roller 5 and axis member 9,A as heretoforestated, the lever" 4 has aratio of 2 to 1`so` as `to donble the ef-`fective leverage 'of the lever 11. Thisfinitial ratio of lever 4increases yto 2% tolas the rail approaches" the fulcrum 5, thusrcoin`-pounding the leverage exerted by the device in the shifting of therail'.- In this present device the maximum shiftoftherail'isapproximately "five inches; In' ractice, two of the devices willvbeemploye 'at the same time, oneV foreach rail, andl arranged directof thetrack. .y y

` In the firstapplication of power,a lar e portion of the leverageexerted through the levers 4 and 11 is generally employed to lift thedead load of the-rail and` its attached ties. `As Athe rail approachescloser` tothe fulcrum 5 in the `movement of the lever 4, this dead loadis transferred closer'to the fulcruni to lighten the load on the lever11 sol as to increase the` power effect `of the latter for shifting' thetrack.` j

A loop handle 21 is provided' at the pawls 19 so that the latter may beVmanuallyraised up theracks 16 to adjust the lever`4 upward under therailfor contact therewith to ac.A commodate for varying distances betweenthe road bed and the rail. This handle may be made integralwith f thepawls and vin` cludes the cross-Web 20: f

Thishandle also allows the device as a whole to be lifted and becarriedfrom place Additional handles 22,22 exi tend laterally outward from thewebs 6, 6

\ of said lever,` said i inglaterally o the racks.

atthe upper `ends of the racks 16to facilitate insertin'glthedeviceunder a rail and pulling stepped drown the rack 16 on'the loweringtl1e`lever`4 from contact-with the rail; `To accomplish this, thefulcrumend of the lever 11 is firstengaged with the steps 17 on whichthe pawls restfand then by raising upward yon' the `lever the load -istransferred from 4the pawlsto the lever 11, whereupon thepawls may be`stepped `down to the next steps 17 belowhby swinging them out by thehandle 21. To ste the lever '11 down the racks 17, ak grip han le 23 isrovided at the outer end l andle being grasped to swingthe `fulcrum endof said lever outward from" the steps. n i n i y i.

' To use the device as a jackfor lifting the railV vertically and not*shifting the same laterally, an attachment is provided for the f1ee`endof the lever 4. `This attachment isin the fo'rrnof` a block `24 havinganin-` clinedunder surface 25 to ride on theroller 5, asshown in F ig.6." The block has a` projection 26 on its top to enter an openling y27at the forward end of the lever 4.

This opening is provided by the web 10,113 shown.

lgThe roller` 5 is grooved, as shown in Figs.

7 and `8,`soasto provide a guide for the block to" hold it from lateraldisplacement. The block when engaged with the lever 4 disposes thesamesubstantially horizontal and main-` tains the lever in substantial"parallelism withv the base plate las the arm 7 is rocked to ,raisel `orlower the member 4 for jackin purposes. LThe pawls 19 act as before anhold the member 4 in its elevated positions.

. Theracks 16may `be providedwith u l,

right guide ilanges`28l along theirouters'i e edges, as shown, toprevent the pawls shift- Thefront of the plate 1 is notched, as `at29to'freceivethe forward or free end of the lever 4 when shifting arail, as shown in Fig. 2.k The web 10 may be setup into the lever 4 sothat the side flanges of the bar embrace Ythe roller 5""as shown in"Fig.8,to guide the bar. As shown in Figs.. 2 and 6, the

roller 5 and the lower end of `the arm 7` work inadepressions orrecesses l, lb in the base 1, so `as to reduce the overall height ofthedevice especially when collapsed, `as shown in Fig. 2, to beinsertedunder a rail. The details of structure shown Vand i describedmay be variously changed and modied without departing fromlhe spirit andscope of the invention. y r
